It usually takes about two months for the knee to bend at full angle after meniscus suture surgery. After the meniscus is damaged, the professional orthopedic surgeon should take arthroscopic meniscus suture surgery, but also with the use of hinged brace, to ensure that the normal flexion and extension of the knee joint, to protect the injured meniscus does not appear to be shifted. About one month after the operation, you can go down to the ground with crutches, but avoid flexion and extension activities of the knee. About two months after surgery, the knee can only do full angle bending. During the recovery period after meniscus suture surgery, it is recommended to choose the right time to perform rehabilitation exercises under the guidance of professional orthopedic surgeons, which will help the recovery of knee function. However, it is not advisable to do functional exercises such as flexion and extension exercises for the knee too early to avoid affecting the healing of the meniscus.
